    摘要： A method for managing a data storage system, consisting of configuring a first cache to retrieve data from and store data at a first range of logical addresses (LAs) in a storage device. A second cache is configured to operate like the first cache. The method further includes configuring one or more third caches to retrieve data from and store data at a second range of LAs in the storage device.The method includes detecting an inability of the second cache to retrieve data from or store data at the first range of LAs. In response to the inability, at least one of the first cache and the one or more third caches are reconfigured to retrieve data from and store at the first range of LAs while continuing to retrieve data from and store at the second range of LAs.

    摘要： According to some embodiments of the present invention, a data storage system may include a plurality of controllers connected or otherwise associated with one or more mass data storage devices. One controller may signal to one or more other controllers an indication as for which data blocks it has received requests. A prefetch decision module on a controller may decide to prefetch some or all of the data blocks associated with a given logical data unit based on data block requests it has received and based on requests received by other controllers. A prefetch decision module on a first controller may signal one or more other controllers to prefetch one or more data blocks associated with a given logical unit and which reside on mass storage devices either connected or otherwise associated with each of the one or more controllers.

    摘要： A method for managing activity of a data storage system including a primary storage facility and a secondary storage facility. The method includes mirroring a first logical unit in the primary facility on a second logical unit in the secondary facility, and receiving a command to perform a data storage management activity on the first logical unit. The method further includes synchronizing the second logical unit with the first logical unit responsive to the command, and performing the command on the first logical unit and the second logical unit simultaneously following synchronization.

    摘要： A method for copying a logical volume in a data storage system, including forming a first logical volume having one or more logical partitions and storing data at a physical location associated with the one or more logical partitions. The method further includes receiving a first command to copy the first logical volume to a second logical volume, and responsively to the first command, assigning the one or more logical partitions to a meta-volume and linking the meta-volume to the first and second logical volumes. The method also includes receiving a second command to access the data in at least one of the first and second logical volumes, responsively to the second command, using a partition descriptor record associated with the meta-volume to identify the physical location, and providing access to the data at the physical location.

    摘要： Disclosed is a system, method and circuit for mirroring data on a data server. According to some embodiments of the present invention, a primary mirroring module associated with a primary server may be adapted to establish data mirroring connections between the primary server and both a primary slave mirroring module functionally associated with a primary mirror server and with a secondary slave mirroring module functionally associated with a secondary mirror server. When sensing that a mirroring connection with the primary server has been terminated, the primary slave mirroring module may establish a mirroring connection with the second slave mirroring module and may reconcile data between the primary and secondary mirror servers.

    摘要： Upon receiving a request for one or a set of data blocks associated with a given data segment, a disk cache controller may retrieve into cache the some part of the entire data segment from a disk. Each data segments on a disk may include a fixed number of data blocks, and all data segments may include the same number of data blocks. Data segments may be dynamically defined and their locations and sizes may vary from segment to segment. Data segments may be defined when data is written to the disk, or may be defined at a later point. A table associated with a cache controller may store information as to the physical location or address on a disk of the starting point and/or size of each data segment.
